If a user requests a u-boot binary in elf format,
they may actually want the stripped u-boot.elf version.
This patch provides the stripped u-boot.elf binary.

This assumes BR2_TARGET_UBOOT_FORMAT_ELF will always result in
building u-boot.elf, but I don't think this is true for all platforms.

At a quick test with a RISC-V build and BR2_TARGET_UBOOT_FORMAT_ELF=y I
got a failure with your patch applied because u-boot is produced but
u-boot.elf isn't.

Thank you for this feedback.  I was not aware that some platforms generate a u-boot file, but not a u-boot.elf file.

I could just use the u-boot file with the versal builds, but I would prefer to use the u-boot.elf file, so that I fully match the way PetaLinux and Yocto work.

Do you have any suggestions for getting the u-boot.elf file, if it is not available for all platforms?  

Would it be acceptable to add a define specific to this version of elf file such as BR2_TARGET_UBOOT_FORMAT_STRIPPED_ELF?  This would still fail, of course, if built with a RISC-V configuration, so I am not sure what to do.

Best regards,
Neal Frager

Do you know if all ARM 64-bit architectures generate a u-boot.elf by default?  

We could do this then:

ifeq ($(BR2_TARGET_UBOOT_FORMAT_ELF),y)
UBOOT_BINS += u-boot
# To make elf usable for debuging on ARC use special target
Ifeq ($(BR2_aarch64),y)
UBOOT_BINS += u-boot.elf
endif
ifeq ($(BR2_arc),y)
UBOOT_MAKE_TARGET += mdbtrick
endif
endif

What do you think?

Best regards,
